If you cannot drive the vehicle 
without f ixing the problem, and you
do not have a spare fuse, take a fuse 
of the same rating or a lower rating 
f rom one of the other circuits. Make
sureyoucandowithoutthatcircuit
temporarily (such as the accessory
power socket or radio). 
If you replace the blown f use with a
spare f use that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
f use with one of the correct rating as
soon as you can.
Look f or a blown wire inside the
f use. If it is blown, replace it with
oneof thesparefusesof thesame 
rating or lower. The spare f uses
